MAX MÜLLER AG / WELCOME

/ History

/ Continuity

/ Innovation

Founded in 1936 by the electrical engineer Max Müller, the company started business in tra-ding with electrical components, mainly for the chemical industry. This relationship identified the need for a sightglass light fitting capable of use in potentially explosive environments. Its development and subsequent market introduction provided the foundation stone for the successful evolution of the business in the specialised fields of process lighting, visual ob-servation and remote monitoring. The light fittings together with ancillary items facilitate the vital observation, and thus control, of physical and chemical reactions inside every type of process vessel: reactors, dryers, mixers, columns, tanks, etc. A branch office was opened in the UK in 1990, followed in 1995 by the subsidiary MAX MÜLLER GmbH in Germany.

Besides the manufacturing of light fittings and explosion proof cameras, the sales spectrum was enlarged by a steadily gro-wing programme of sightglasses, today covering a broad variety of different types of fittings, including applications in sterile areas, clean rooms and biogas plants.

The present managing director, Dr. Ing.-Chem. Hans Georg Müller, joined the company in 1974. Under his direction, the light fittings business was incorpora-ted into the MAX MÜLLER Holding group.

Dipl. Ing. Roger A. Blenny, member of the management board, has been technical mana-ger for more than 25 years. Dipl. Ing. Stéphane Blenny heads the development and quality control department.

Continual research, development and feasibility studies ensure that the pro-ducts of MAX MÜLLER AG are leaders in their field. As an innovative com-pany, over the years several technical milestones have been created:

With our renowned quality and our experience gained over the years, together with our dedicated and knowledgeable staff, MAX MÜLLER AG is an ideal and competent partner to provide best adapted solutions to your process illumination and sightglass problems.
